I'm already taking my vegetarian guest to Oleana on Friday night. Any recommendations for a good veg-friendly spot for dinner Saturday? She doesn't want to spend too much, so the Degustation of Vegetables at L'Espalier is definitely not an option. I'm in East Cambridge, and am happy to travel to Beacon Hill, Back Bay, South End, Somerville, or JP. I'm also looking for a good brunch spot that won't break the bank. I'd really like to be able to make a reservation for brunch, though, so I know that rules out some of the best, chowish brunch places. Any advice?
