West Side Lounge 1680 Mass Ave. Cambridge 617-441-5566 This restaurant is what Cena's was reincarnated as. It does serve non-vegetarian. I brought a non-vegetarian friend there. I ordered the "Vegetarian Pri Fixe" for $25. It's always a vegan meal, complete with soup, salad, and entree. Apparently, it differs from night-to-night (or perhaps week-to-week). The soup I had was some sort of pumpkin soup. The salad was interesting, with what seemed to be Tat Soi (like bok choi) leaves and grilled cauliflower. The entree was a mixed-mushroom risotto. 'Though very good, I unfortunately left still hungry. (The dessert menu seems non-vegan. I had my non-cheese cake I had made for T-Day for dessert when I got home. That filled me up!) This restaurant may be a bit too pricey for a monthly dining-out thing. And, even if it were considered, someone would have to negotiate with the cook for have a little variety (unless everyone wanted the standard fare!).
