We used the info centre to book a cab from the airport and due to our own error we messed up the dates. When we realized this, and frantically emailed them they were still extremely helpful giving us advise on how to get to Samara. We booked a tour through them and stopped in multiple times for help with buses etc. They are willing to help with anything and everything. I overhead them telling others in the shop if they have problems with the taxi to have the cab driver call them to translate. When we told them we were vegetarians they told us a list of places to eat. You also get a discount at tons of local restaurants if you show them their business card. Highly recommend stopping in even if you aren’t planning on booking tours… They have tons of information and resources helpful to all travelers.
