you can taste in every bite. Bonus: Sundays are dog friendly days so bring your baby along.
My girlfriend and I had a lovely lunch on the second floor. Note there is no seating on the first floor except for one table outside. She had a large salad in which she requested her favourite ingredients. Citron was very accommodating to her request and supplied salad dressing on the side. I had the lunch set with an awesome feta and spinach quiche, a small side salad, roll and spicy cumin carrot soup. You can have a full lunch meal for under 1,500 yen (set menus are 1,190 JPY without tax and drink). The interior is simple industrial chic with a bit of French. They also have an amazing looking selection of desserts, but due to the waist line, I skipped.
Citron is open for lunch and dinner, and takeout can also be requested. Here is a link to their bi-lingual menu. Recommend keeping this place on your list for lunch if you are in the area shopping or going to the park. They also have an express branch in Otemachi for takeout and cater for Tokyo parties info@citron.co.jp .
