This green-tinted diner is possibly the most stylish restaurant in ever-hectic Siam Square.

Grassroom matches its preponderance of potted plants with a dedication to locally-sourced ingredients. The Asia-spanning menu emphasizes familiar flavors made with playful tweaks, such as the appetizer of nam prik ong (Northern-style chili dip) with ricotta cheese and crostini bread (B140).

Those with larger appetites can order the Grassroom double burger (B295) with its Thai-style minced pork and salted fish patties, while the herb salad moo hong (B200) comes with Phuket-style braised kurobuta pork.
