Zinc is a good place to go to when the weather is nice, because you can sit outside and enjoy the warm weather and sunshine. The food is very good (frittatas and egg salad are excellent) and the desserts are quite tasty too. The prices are a bit too high (in my opionion), but the quality of the food is worth it.
Since it is located on Cedros in Solana Beach, you can walk along the design district, do some shopping (or window shopping, as I do) and then get a good meal. It can be too crowded during the tourist season, so I as a local tend to stay away during that time (unless I am meeting friends there), but I try to make it to Zinc as much as I can the rest of the year.
