As others have noted, an unexpectedly satisfying Mexican restaurant where you wouldn’t expect to find one. I particularly like the tinga and mole preparations; we were recently delighted by some house-made dulce de leche ice cream (have it with hot churros and chocolate sauce). The tortilla chips are fresh; the guacamole is hit or miss and I wasn’t too into the salsa brava, which tasted more like enchilada sauce and I really wanted something fresh. But I can overlook these flaws because I know how hard it is to source fresh jalapeños and tomatillos in Germany, and because Mextreme offers something else rare around these parts: outstanding customer service. I’ve had three different servers at this point, including one in training, and they were all friendly, helpful, and well-informed. Little wonder this place is so popular! My only regret is that they are not open for lunch!
