This is the best Thai I've found in Pittsburgh.
I generally don't bother with anything besides their pumpkin curry (veggies + tofu), because it's ridiculously delicious. Creamy, spicy, subtly sweet...it's also a perfect serving for one sitting.
To avoid being cramped, just try a weeknight or go with a small group. The atmosphere is adorable and great for a date, and they're BYOB. Excellent for takeout too!
