Hi! Thanks for the feedback! You're quite right, since we're open from early morning til late in the evening, we have quite a lot of items and different foods available at different times. We have got rid of the chalkboard and now have a bit more clear version of the menu. We have decided not to use digital screens as we feel they would ruin the atmosphere of the restaurant. As for items no longer being available after queuing, we are very sorry about that. If you were in line before the menu changed to the lunch menu, you should've been able to get the breakfast item despite the menu changing for lunch. The reason we need to be quite strict with this overall is that we have very busy lunch hours and need to get started on it right away.
Still glad to hear you liked the food and hope to see you again! In the meantime, we will keep working on the menu and the queuing to ensure a smoother experience for everyone!
