I was there ~10 days ago and can confirm the portions (at least in the to-go cups) are noticeably smaller. There is a "premium" margarita they will make fresh... It's ~$18 plus tip, which is a bit tough to take in general but especially so with decreased portions. The other "hack" for a freshly made margarita is to specify the type of tequila you want. I have always enjoyed La Cava and think several members of the staff are great, but have to say between the line to get in, the pre-made drinks & rushed service, the prices and now the portions, I think I may skip it next time.
