Perhaps the designer used Belwe but redrew the 'W'. A big improvement.

i was a bit thrown off because it was so rounded... but i guess you enlarged it from
http://www.tacojohns.com/ ?
the E is bit different in the top. weird.
it must be Belwe, and like Scoles said, the W is fixed up. and if you look closely at tacojohns.com, the white space to the right in the W is too big... which implies that they simply removed the little flag thing and put a serif there.
