Not a problem! Here are some others that I have enjoyed. Please feel free to ask me anything about these restaurants or any others in Boston/Cambridge. In the past few years, my b/f and I have slowly tried to eat at most of the veg-friendly places around here.

Cambridge:

Addis Red Sea - An Ethiopian restaurant. Their substantial vegetarian menu is entirely vegan, and they recently opened a new location in Cambridge.

Border Cafe - Tex-Mex/Cajun, and a Harvard Sq. favorite. Loud, noisy, and always crowded (expect a substantial wait on the weekends), but the food is excellent, and the service is quick.

Veggie Plant: - Another Harvard Sq. restaurant. I think that it is only okay, but their purely vegetarian/vegan menu is extensive.

Oleana - In addition to what I mentioned in my earlier post, Oleana has a dedicated free parking lot (on the weekends for sure, not sure about weekdays) across the street from the restaurant.

Boston:

Bamboo - Consistently excellent Thai (and technically in Allston). Stop in there before dining and pick up a parking permit to park for free at the nearby Whole Foods!

Teatro - An upscale/trendy Italian restaurant. I am a fan of their vegetarian dishes, though they are only a few.

Ivy Restaurant - Similar in ambiance to Teatro, they specialize in American/French "small plates". I found the menu to be vegetarian (not vegan) friendly, and the food to be excellent. One of my favorite "nice night out" restaurants in Boston.

Indian food is by nature vegetarian friendly. Here are my favorites in Boston:

Kashmir - Good, if expensive, brunch.

Indian Delight - Not much to look at on the outside, but their food is fantastic. It's located in Kenmore Sq., and if there is no Red Sox game, parking is a breeze.

Site: None that I can find.
