As part of the album's promotion, Hemingway went on the Café Belga Tour [pl], which included concerts in Poland, the United Kingdom, and Ireland.

[1] As a result, Hemingway expedited the release, uploading the entire album to YouTube on July 12, offering it for free digital download on his website, and starting pre-sales in the Asfalt Shop.

The physical version of Café Belga included the bonus mini-album Flagey [pl] and an interview recording with Marek Fall.

[8] Piotr Markowicz from Noizz.pl [pl] compared the production to Hemingway's earlier work: "departing from post-trap schemes towards a more spiritual and vaporwave electronic style".

[9] According to Maciej Wierno from Noizz.pl, Café Belga has a "stronger and more difficult-to-digest" tone compared to Hemingway's previous solo work, Szprycer [pl] (2017).

[12] Jarek Szubrych from Gazeta Wyborcza remarked that the album's musical layer includes "slow beats that harmonize well with humming under the breath, as well as dynamic tracks that could be danced to".

[10] Łukasz Łachecki from CKM wrote that "despite attempts at technical experiments – accelerations, multi-syllabic rhymes, or enjambment – we still get the impression of encountering monotonous, rap staccato".

[19] Cieślak summarized the album by saying: "Taco, blasé or perhaps tired of the hustle and bustle of Warsaw and the commercial success of Taconafide, heads towards Brussels to detach once again from the demons of fame".

The lyrical subject compares his life to a film directed by Stanley Kubrick, with references to several of his works: The Shining (1980), 2001: A Space Odyssey (1968), A Clockwork Orange (1971), and Full Metal Jacket (1987).

[15] Sobczyński compared the song Abonent jest czasowo niedostępny to Drake's work and Taconafide's single Tamagotchi [pl], calling Borucci's beat "bouncy".

[18] Sobczyński also wrote that Motorola is reminiscent of Taconafide and described it as a "strongly hikikomori track reflecting Huxley, Black Mirror, and a longing for a world that no longer exists".

[18] The lyrical subject paraphrases the song Szklana pogoda [pl] by Lombard[19] – according to Przemysław Gulda of Gazeta.pl, the line "szklana pogoda, żyły niebieskie od mefedronu" ("glass-like weather, veins blue from mephedrone") serves as a metaphor for sociopolitical changes, particularly in urban life, that have taken place in Poland since Lombard's hit was released.

Sobczyński described the track as "dense, highly visual rap paired with Borucci's lazy beat, sounding like a drug-induced comedown at 4 AM",[18] while Łachecki identified Metro Boomin as an influence.

[21] The song ends with a dialogue from the film Cold War (2018), where an embassy worker from the Polish People's Republic accuses Wiktor Warski of lacking love for Poland and betraying Poles.

[23] Jarek Szubrycht from Gazeta Wyborcza compared Café Belga to Hemingway's previous albums, stating that it was better written, with a more varied and successful musical layer.

[13] Dawid Bartkowki from the CGM portal wrote that the album "finally brings a lot of freshness to his [Hemingway's] discography" and called it "the return of Taco that you want to listen to until the end".

[12] Przemysław Gulda from Gazeta.pl gave a mixed review, pointing out that some songs sounded like they were made in a hurry and were not polished, although there were "truly brilliant and monumental fragments".

Gulda summarized: "Taco, still spinning in the same circle of themes repeated to the point of boredom, still manages to surprise with an unconventional approach and form that goes beyond the scheme he sometimes seems to fall into".

[7] Maciej Wernio from Noizz.pl called Café Belga "a solid album" and one of the best in Hemingway's discography, while commenting on the rapper's development: "Still, he does not quite manage to fight with his demons, such as over-productivity, blasé attitude, and the burden of being the self-proclaimed 'voice of a generation that has nothing to say'".

[15] Bartek Chaciński [pl] in his review for Polityka pointed out "apt references to both mass and less mainstream culture" and "ease in enchanting with comparisons", but criticized Hemingway for showing "slight fatigue with the convention" and overusing Auto-Tune.

[26] Similar accusations were made by Ilona Chylińska in Opcje [pl], stating that while the lyrics and album concepts were positive, the rapping itself could be described as "mediocre", which was also linked to the excessive use of Auto-Tune.

[32] On 26 July 2018, Café Belga debuted at number one on the OLiS chart, marking Taco Hemingway's third consecutive album (after Szprycer and Soma 0,5 mg) to achieve this feat.

[33][34] The next day, Asfalt Records announced that the album had reached the threshold for a Gold certification – awarded by the Polish Society of the Phonographic Industry for 15,000 physical copies sold in Poland – within two weeks of its release.

[41] OLiS is a national chart compiled by the TNS Polska [pl] agency based on physical album sales (it does not include data on digital downloads or streaming plays).
