I LOVE bagel & bagel!!! You simply must try the "everything" bagel...it has, as you may have guessed, everything on it and in it. Fabulous toasted with plain cream cheese. And the wheat bagels with the sweet basil cream cheese are awesome. Probably the best thing about this place is that they dont' stop at just making different flavored bagels - the cream cheese offers a delightful variety as well. You can also buy extra cream cheese and take it home so you can actually have a bagel and cream cheese for breakfast the next morning (I actually go out of my way to find one of these places since there are none near my apartment).
Oh, and remember, the sandwiches are made in advance...nothing made in advance is ever as tasty as the freshly made...
It doesn't matter which location you go to. Shakey's is equally bad all across Tokyo. It is an American chain that has been localized far too well. The pizzas lack adequate cheese topping, and choices run the gamut from classics like the wasabi barbecue chicken pizzas with corn to mochi dessert pizza. They've attempted nachos, but the toppings come on pre-seasoned Doritos. And the sausage doesn't sound too bad, until you look at the picture and realize the coiled shape is far too similar to some less desirable aspects of human digestion. The restaurants are perpetually loud and chaotic, with a frantic staff doing their best to accommodate all demands. If you're forced to patronize this chain, go for the curry fries. It may be the only decent thing on the menu.
Just another sandwich shop. Nothing to write home about, but if you're sick of convenience store sandwiches with mystery filling, you'll probably find Subway to be the end-all and be-all of sandwiches. This is, unfortunately, just a side effect of having been away from home and a plethora of tasty sandwich shops for too long. They also have wraps and salads. They just as mundane as the sandwiches. But, if you want a healthier alternative to MacDonald's, get yourself to the nearest Subway.
