Archi's is a small chain restaurant in Vegas that serves Thai food. They have an extensive menu, and they cook everything from a spice level 1 (not spicy) to a spice level 10 (my mouth is on fire!).
The prices are very reasonable for the amount of food that is served. My favorite dish is the Pad Ka Pow, however, their Tom Kha soup is also tasty. On a chilly Autumn night, there's nothing like a bowl of warm Tom Kha. The hints of cilantro and coconut milk really make for a pleasant experience.
Why 4 stars instead of 5? I made the mistake of ordering the Beef Salad, and the meat that came with it was quite fatty. Also, there service is 'ok', but not great.
