Will be visiting Brooklyn later this month. Arriving on a Saturday around 11AM. Would like suggestions for a nice place for lunch. The main event of the weekend is dinner at Eleven Madison Park later that day, so I'm looking for a Chowhound worthy lunch destination as a prelude to that. (For me, a slice at DiFara's would fit the bill, but I want something without the hassle factor and in Park Slope). Another wrinkle to throw in here is that my wife is vegetarian (not vegan, so eggs and dairy are OK), but I am comfortable in my "flexitarian" skin. High end place, low end place, no matter - YOU help me decide. Thanks!
