If you work in and around London Wall, Barbie Green, an Australian-style cafe situation from the people behind Timmy Green in Victoria, might be a useful spot for a coffee or a bite to eat at any time of the day or night. The food here ranges from solid sweet and savoury brunches, through to pizzas and salads for lunch and dinner. You can also get chicken parmigiana that’ll keep you nourished for about a week. It’s open till 11pm through the week so it might also be useful if you get lost on the Barbican Highline and find yourself around here after a show.
