Went today for lunch. Mixed Feelings. Parking lot (next to CPK, west of Overland south side of Venice) crowded. Line to order. Much longer wait (they give you a beeper -- mine didn't go off, I would have waited if i didn't recognize the party before me getting theirs and go up on my own). I ordered a double-size bbq-bacon-cheddar which had onion strings -- $6.99. Burger was smaller than I expected for a "double" at that price, maybe a quarter-pound. It was indeed tasty, the smashing process made for a good sear char, so the burger had a lot of crusty goodness. I liked the bun and the generous onion haystack strings. But I could only find a seat on the patio, and the sun made it hot. Simple french fries ($1.99) and fountain drinks ($1.99) were on the expensive side so I settled for water. I am signing up for their online offers, and would go back -- non-rush times -- for a 2-for-1 burger or free side or milkshake. But at twice the price and so much more time, a double-double at In'&'Out or a bigger burger at Hole-In-the-Wall or The Shack will rank higher on my rotation.
Note-- Moderators, I know Smash Burger is a chain. But it is brand new to L.A. My review is very focused on this one new location, and i beg you to keep this on the L.A. board.
