Earlier, Alex posted that Amtrack's burgers cost $16 -and from what I can tell, they aren't even very good. If you want to shell out $16 for a burger that's actually worth the cost (and happen to live in Japan), then you might want to head over to Wendy's.
Sure, their stateside burgers might not be all that great (at least, the ones near me certainly aren't), but the chain's Japanese offerings are totally classy. Take, for example, the surf and turf burger that features lobster or the caviar and lobster sandwich served without beef.
Would you pay $16 for a Wendy's sandwich if it had lobster on it?
