For a friend's birthday, I want to take her to a nice, leisurely lunch. The lunch would need to be on a Saturday due to our schedules. Most of the places we originally had in mind only serve lunch Monday thru Friday. We are open to cuisine but would prefer somewhere with inventive vegetarian options. Also we would love an interesting cocktail list or wine list. I'd like to keep it around $50 a person, but for something stellar, I would go up. If its somewhere where we can walk around afterwards, like an interesting old town, that would be a bonus. Thank you!
