Last night we had a reservation at Xel-Ha, the new Yucatan-style Mexican restaurant that had Chowhounders had recommended but which we'd not yet been to. When we got there it was closed - no sign saying anything about it. We called, and the answering machine said something about a lease problem and that they were hoping to reopen at another location. We hope it all works out; we're sorry to have missed sampling their cooking; we'll certainly go if they reopen; but we wish we'd been called since they took our number when we made the reservation. As a result we strolled south one block to Kan Zaman and had a delightful time. The beef shish-kabob was the hit of the night.
