Traditionally, Laab is often prepared with freshwater fish in Northeastern Thailand. For our version, we chose cod cheek — one of the most tender and delicate cuts of fish — to create a cleaner, bone-free experience while preserving the bold flavors that make this dish so beloved.

Spring’s Cocktail Menu
FOOL’S ERRAND

Rum | Triple Sec | Kiwi Prosecco Shrub | Lime | Pineapple | Grapefruit Bitters | Pink Himalayan Sea Salt

A beautiful mess in the best possible way.

Tropical fruit, bright citrus, and a touch of sea salt collide in a cocktail that’s equal parts refreshing, chaotic, and dangerously easy to drink.
