Sup fellas?
Been gone on bidness/vacay for a bit and had time for a few beers..... not to say that I enjoyed them all, but tried most every Japanese beer and a few Japanese craft beers... and some shitty Mexican beers.
The usual suspects were... Corona, Modelo, Negra Modelo, Asahi, Asahi Black(bar far the best and most consumed on my part), Kirin, Sapporo.
But.... I found a cool American Craft brew pub in Tokyo that had an AMAZING selction at ASTOUNDING (my wallet had to go home 3 days early) prices.
Their list of cool stuff(not all inclusive):
Alesmith Speedway, Three Floyds Dark Lord, Gumballhead, Popskull, Lost Abbey Serpant's Stout, Lost & Found, Founders you name it they had it all, Stone Vertical Epic 10 10 10..... it was insane!!
their tap list...
