As foodie-elect of my work friends, I am looking for a nice celebratory holiday lunch spot for us in mid-December. We are four professionals who want it all -- atmosphere and delicious food-- and one of us has gluten issues. We work in Cambridge by Harvard Square but close to Storrow so could easily go downtown, Back Bay, etc. We have celebrated other years at Henrietta’s; we’re looking for an alternative. I know that Upstairs on the Square has a nice fireplace but the last several times I've been there -- over 8 months ago -- I was underwhelmed. Thought about Gran Gusto but the ambiance is not that compelling. We recently ate at Area Four and I just sent a few of the group to Catalyst. I don’t tend to go to the hotels but am wondering if there is one that might be atmospheric, have solid food, and not be outrageously expensive. Aside from the gulten, we are very open minded. Thanks in advance for any suggestions.
