Mission Burger Co.B+

3600 S Lamar Blvd, Austin, TX 78704 · Vegan restaurant, American restaurant, Brunch restaurant · South Lamar

Crowd-pleasing vegan burger spot with standout smoked mushroom brisket and friendly vibes; great flavors, occasional order delays and sauce-heavy items; prices mid-to-high for fast-casual.

The verdict

Mission Burger Co. delivers solid neighborhood dining through exceptional food quality—particularly the smoked mushroom brisket and breakfast sandwiches—paired with warm, attentive service that welcomes both vegans and non-vegans alike. However, inconsistent execution with occasional oversauced items and fries, combined with notable delays on delivery orders and limited indoor seating, prevents it from reaching higher territory.

About this restaurant

A lively fast-casual spot on South Lamar, Mission Burger Co. greets you with a warm cookie and friendly counter help, then sends out hearty vegan comfort food to a cozy patio. Diners praise the welcoming staff and keep talking about the smoked mushroom brisket, with one guest noting it "tasted unbelievably meaty for a plant-based take." Space is casual and shared with a cafe, with limited indoor seating but a relaxed, sunny vibe. The cooking centers on vegan comfort classics done with care: double-patty Impossible burgers, Just Egg breakfast sandos, and loaded fries, plus that house-smoked mushroom brisket. Flavors often land big and satisfying, especially the Mission Burger and breakfast items, though a few diners found some items oversauced or fries under-crisp. Prices sit mid-to-high for counter service, but portions are generous and the staff is eager to explain proteins and options. Families will find it approachable: nuggets, fries, shakes/soft serve (per reviews), and straightforward burgers make ordering easy for kids. There is no formal kids menu, but the familiar choices travel well to the patio. For picky eaters, ask to go light on sauces and choose simpler builds; gluten-free buns and lettuce wraps help, though be clear about special requests at ordering.
