I enjoy browsing at the Mustard Seed Market. The downstairs is a full natural foods market, and the upstairs is a full service restaurant.
Starting with the market - your full compliment of natural foods products, including a nice health and beauty section. Prices that you'd expect, i.e., rather high. Wonderful cheese and olive selection, at somewhat reasonable prices. The wine selection is outstanding, and the descriptions are helpful. The wine prices are excellent - you'll always find something to try for less than $10 a bottle. Awesome prepared foods section as well - sandwiches, sushi, falafel, pizza, breads, chicken, etc... And the prices aren't too bad. You can also buy sodas, teas, waters, etc... by the bottle to complement your carry -out lunch. The salad bar is extensive and lovely, but I think rather pricey.
The upstairs restaurant I am not too impressed with. A bit overpriced I think, and not a great selection. You're better off buying something downstairs and taking it to the park to enjoy your lunch.
