Sedate Galt Ocean Mile may be known more for its old-fashioned snowbirds than for its newfangled eateries. But Bistro Double U is paving the way for change with appetizers like the house-cured salmon quesadilla with mustard dill sauce and salmon caviar; salads such as arugula with warm potato dressing and goat cheese croutons; and entrées that include pan-seared scallops and crawfish tails in cognac bisque. Proprietors Uli Dippon and Udo Mueller, who is also the chef, run a tight but almost informal operation, saving booths and tables in the smartly decorated dining room for those who make reservations but gladly seating walk-ins on the patio outside. After all, eating well on the spur of the moment is what contemporary dining is all about these days. Prices are also reasonable, and the wine list small but select, with about two dozen choices available by the split or glass. So, Uli and Udo, how 'bout a Double U 2?
