We chose Mensa to try something new, and to celebrate my birthday, and we were extremely happy with the entire experience. I sought an interesting meal, featuring fresh fish and presented with unique flavors, and I found Mensa's approach, fusing tastes of Japanese and Korean cuisine with those of Portugal to be savory and spot on. The dining room is complemented with outdoor seating; we sat inside and found it quite comfortable. We started with a couvert of bread and compound butters, and then shared a "travessa" of tuna in a teriyaki sauce and coated with natural and black sesame seeds. Sides of rice with dried fruits and nuts, and sauteed napa cabbage complemented the tuna with their textures and flavors. Our pairing of a Portuguese Chardonnay from Dão suited the meal better than the Sauvignon Blanc we had started with as an aperitif--not the wine's fault, though! The service was excellent throughout, and our meal capped with a gratis shot of aguardente to celebrate my day.
