Thai Kitchen is a great hidden gem. It's is on Mass Ave parallel with Davis Square. Just a few minutes walk from the T stop. It's a no-frills atmosphere, but the service is so great that you feel like you're in a 4-star restaurant. I recommend any of the "all-day specials" you get hot and sour soup, an entree and an appetizer all for under around $9. And then at the end of the meal you get free ice cream, and yummy candies with your check. Your water glass will never be half-empty and my favorite part is when you leave, the staff say "Goodbye" and "Thank you" - whic I really appreciate. Check it out - it will become your new favorite neighborhood restaurant!
