Chaya Pasta cafe is a good place to recharge your batteries around Tokyo station. Conveniently located a few minutes away from the gates, the portions are hearty and abundant.
To get there, take the stairs down to the underground Yaesu mall and walk to the end of Lemon Road. The cafe runs two locations almost side by side; one is a bit fancier with tables and a waitress while the other features a counter designed for solo dinning or at most two people. There is no big difference in prices, but Chaya II, the one with the tables, is slightly more expensive.
I ordered one of the lunch specials, which featured two types of pasta, a salad and a bun. One of the pastas is fixed (mine was a penne with a spicy arabiata sauce), and the price of the set menu changes depending on your choice of the second pasta. I picked an olive oil, scallops and garlic pasta which turned out to be rather good, I suspect because it was swimming in olive oil with perfectly browned garlic. The salad was refreshing, but they could have left the bun in the kitchen.
Set menus range between 900-1200 yen, while the a la carte menu ranges between 600-1200 per portion. They offer half portions, which might be a good idea if you are not up for a big helping of carbs. A small wine list could add a touch of class to an evening meal. Overall Chaya is a no-frills place to recharge batteries and indulge in some comfort food at reasonable prices.
