Too often, American restaurants that serve foreign food simply display a few trinkets and flags and stereotypical pieces of artwork to appeal to diners' imaginations. But Fou Frog is an exception. It doesn't feel like a French restaurant in the United States. It feels like a real French restaurant. From the lampposts on mirrored walls to the moules and frites on the plates, there is nothing inauthentic about this place. It's an ideal spot for drinking some red wine and finishing a meal with a salad, taking a two-hour lunch and exchanging banter with the chatty and personable wait staff. The decorations consist of posters advertising French tobacco and liqueur. Any homesick, aperitif-loving Francophiles stranded in this town -- which is as far from any U.S. border as you can possibly get -- ought to head downtown right away. Just don't become so convinced by your surroundings that you accidentally follow the European custom of not tipping.
