The menu runs both à la carte and as a Grand Tasting Menu, with Chef Thai using the tasting format to dig deeper into the history behind the cuisine. Dishes reviewers mention often include papaya salad, octopus, ribeye, a seafood stew, prawns, wings, and jasmine rice, alongside small plates built for sharing.
The restaurant has drawn sustained national attention. It's been a repeat James Beard semifinalist for Best Chef Great Lakes (2023, 2025, 2026) and a 2025 finalist in that category, following an earlier run of Best Chef semifinalist nods in 2019 and 2020 and a Best New Restaurant semifinalist nomination in 2018. Michelin awarded HaiSous a Bib Gourmand in 2025, and Eater has named it among its best-of picks for the city.
