We don't know for sure if Justin Bieber was stoned Sunday ... who are we kidding, he dropped more than $240 on fast Mexican food -- of course he was.
Justin and crew rolled up to celebrity hotspot Pinches Tacos on the Sunset Strip in West Hollywood on his way to Coachella and dropped $185 on a South of the boarder feast, consisting of:
-- 13 steak tacos-- 9 chicken tostadas-- 8 chicken tacos-- 3 taco plates-- 1 steak burrito-- 1 chicken burrito-- 4 orders of chips and salsa-- 10 bottles of water-- 9 Mexican sodas
Justin waited in a Mercedes van while someone from his crew picked up the grub and left a $55 tip, on Justin's credit card.
Ese Pinches Bieber.
