There's a street in my hometown of Costa Mesa, CA, that has FOUR breweries on it, all about a 5 minute walk from the furthest ones away from each other.
Each of them are just a little different, but all offer nice outdoor seating. In no particular order, and have to link 3 Yelp profiles 'cuz my work blocks certain sites (bleh):
Bootleggers: doesn't have their own food, but you can easily order from "The Lab" next door, which is a conglomeration of hip restaurants and shops. Nice patio, and the inside opens up to the patio, so it's a very open-air type of concept. Plenty of beers, wide variety. Couple of TVs for sports. Probably my favorite out of the four since they have a wider variety of brews. Wish they had their own food, though.
Green Cheek: used to be Barley Forge, which had a good variety of beers and a fairly extensive menu. Sold to Green Cheek a couple years ago. Not as much selection in terms of beer (I mean, they have THREE hazy IPAs), but they do have insanely good smashburgers. During the first part of COVID, they redid part of their parking lot to feature a huge covered patio with plenty of picnic tables. A favorite for those with kiddos and/or dogs to come enjoy the patio on a sunny afternoon.
Gunwhale: used to just be a smaller tasting room with small patio, but when COVID hit they were able to convert parking into a larger patio space with patio tables and food truck most nights. More of a "beer snob" type of selection. A buddy of mine who runs a cold brew coffee company did a collaboration with them on a cream ale, which is pretty cool. I find this to be my least favorite of the four, but my buddy from Denver who comes into town a few times a year swears by it, so I end up going from time to time.
Salty Bear: solid overall, with a nice wide range of beer selections. Open-air concept inside, with a large patio (that got larger during height of COVID). They will have food trucks or "pop-up" type of food purveyors, which adds to the popularity.

So I think, in general, to have a great concept you: have an "open-air" indoor space, with plenty of outdoor seating; some kind of food option; and have a wide variety of beers.
