This may not be new, but it's new to me. Recently I've eaten at Thali and then Pacifico for lunch and ordered from a prix fixe lunch menu. At Thali they change it weekly. At Pacifico, my meal of "Ceviche de Camaron Estilo Ecutoriano", shrimp with tomatoes and avocados, "fish tacos" and sorbet was delightful, at $16.95.
Images of Thali lunch from my Blackberry. Again, I have eaten into my dishes before photographing them; how shameful. The five (four showing) crispy shrimp were fabulous as was the surprise piece of tikka tuna (half of it's missing). They did not say what kind of fish it was on the menu, so I was very pleasantly surprised. Service was fantastic, as usual.
Additionally, these two restaurants are open on Saturdays, which is a rarity, downtown.
I really like this concept and wonder who else is doing it?
