Though outside the streets may be full of rain and slush, inside Pasteur, it's always sunny and tropical. Pure white walls carry the natural light from the front windows all the way to the back of the space, and woven chairs and soaring greenery lend a shore-side air to the space without relying on tables sprinkled with sea salt. What began in 1985 as a restaurant serving one simple dish—Vietnamese pho—has blossomed into a bustling, upscale eatery serving cuisine from all regions of Vietnam. Flavors of lemongrass, coconut, and garlic underpin a menu highlighted by seafood dishes: monkfish in a curry tumeric sauce, salmon baked in a clay pot, and whole fried snapper.
