I recently learned that Beacon is doing a 'true' American BBQ on Sundays and Mondays to go along with their special burger nights. The menu looks authentic enough, but they don't mention if the food is actually smoked low and slow or just boiled/grilled.
BBQ sampler platter for 2 or more ￥2200 per person includes
BBQ プラッター ￥2200 (１名様) ※2名様よりのご注文となります。
Ribs, pulled pork, chicken, beef, hot links, corn muffins and choice of 2 sides
I'll try to go soon and report back. Perhaps I'll even grill the waitstaff about techniques, I'm picky about my 'cue. :-)
