To start off I am not a huge sandwich guy, so a $10 sandwich should be an ethereal gift to get my praise.
My $10 tuna "sandwich here" was not quite what one would expect. It was more of a tuna bruchetta plate served on 3 thick slices of rustic bread toast. The tun was a caned oil packed tuna, decent quality but still canned with some nuts and grains. On the texture size the nuts and the bread made it a hit, however on the flavor side it need an acid to balance out the flavors.
My biggest gripe was, that I was still hungry after my $10 lunch.
