The River Market is what you might call a sandwich-rich environment. You can find tasty offerings at the Coast Cafe, Boulevard Bread and Tropical Smoothie Cafe. Now you can add Rivershore Eatery to that list. It occupies the spot vacated by Brown Sugar Bakery and its sandwiches may just be good enough to keep them there for awhile. We tried the Club Sandwich, made up of a thinly sliced chicken breast, lettuce, tomatoes, green onions, avocado, Parmesan cheese and seasoned oil, all on a nice, puffy, not-too-chewy ciabatta role. A friend had the Chicken Ranch Club, which is basically the same thing, just add bacon and ranch dressing (both were $5.99). The sandwiches were wonderful and filling, served with just the right amount of chicken and the veggies were fresh. Rivershore also offers salads, baked potatoes, nachos and chicken wings. We tried the latter but were not impressed — too much lemon flavoring. The sandwiches will keep us coming back. 400 President Clinton Ave., in the River Market. CC. 501-244-2326. 10 a.m.-6 p.m. Mon.-Sat.
