The marshrutkas taken from Batumi to Kashuri and then to Tbilissi was something! We thought we were travelling economic class till now, but there is another class belowJ , with feet into car tyres for 3 hours and our backpacks resting on our legs. The driver managed to fit 18 persons in a 12 passenger minibus. There is some sort of solidarity between the travelers accepting to squeeze in those who have waited so long along the road. The lunch stop was a great time with mini hamburgers and purée. One Lari toilet break before boarding again. And the final leg to Tbilissi with the same CD full of lively Georgian songs for the 5th time!
The Tbilissi metro is a typical fast and efficient soviet style metro. I felt like in Tokyo unable to read any station name, counting the numbers to disembark at the right station.
