Conor McGregor ain't letting gnarly leg surgery keep him away from a good meal ... the UFC star hit an L.A. hotspot for dinner Thursday night, and vowed to TMZ Sports afterward he's on his way to a big recovery!
The 33-year-old -- who broke his leg during his fight with Dustin Poirier on July 10 -- was in great spirits while crutching around Craig's in West Hollywood.
You can see in the footage, he was moving pretty well despite having major surgery less than a month ago ... getting around a mob of people and into a car without much assistance at all.
