We LOVE Beaches & Cream for wonderful burgers and ice cold beer, right at the BC!
You can also walk or take the ferry over to the BW area to the ESPN club or the Brewery. We have had a great lunch (and dinner) at the brewery and I love it because you can eat outdoors at the BW. Recently my sil and I had an appetizer dinner at ESPN that was terrific.
Last time I was at the YC (October) the crews cup lounge wasn't serving food - hopefully this was temporary but I thought it worth a mention. It was about 6ish and sil and I wanted a quick retreat ~
