This was the first time that we were at Shinjuku station on Sunday morning at 7 a.m. from Haneda airport. We were starving and tired and need a place to sit down and have food and a cup of tea. Unfortunately, no coffee shop opened in the morning on Sunday. However, I know Shinjuku station very well after many years in the past in Japan. we found a little shop where we can have Onigiri (rice with seaweed and salmon inside, or umeboshi inside etc. We enjoyed our food and miso soup. It was fun to choose what we would like to have and a cup of tasty "miso soup. After that we still need a place to have a cup of tea or coffee and take a rest after putting our back packs in the lockers.Then, we walked to Keio Plaza Hotel which is on the west exit, it takes 5 minutes more to walk to Keio Plaza. We felt so relieved and wen to All Day Dinning Jurin. It's too bad we had our onigiri already so we only ordered oatmeal with berries and a cup of tea and coffee. At this Jurin one can have western style buffet for 3,000 yen all you can eat. Next time we will definitely go there if it is on Sunday morning!
