In about a week some of my friends and I will be going to visit one of our goes to college in Boston, we are planning on taking her out to dinner for her birthday and are brainstorming where to go for dinner. We are looking for a restaurant that isn't too pricey, but has either a fun, exciting atmostphere, or is somewhat unique and has a cool ambiance and design. Perferably in or around the Harvard Square, or Quincy Market areas, or within a short cab ride from those places. Any suggestions would be greatly appreciated. Even if there were any neat, non-expensive dessert places that stand out those suggestions would be great as well!
