Bus and Food and Clothes to Mt Taibai

I saw on another website the no. 2 bus leaves from the train station at 7:30 and am a touch worried that we might miss it - sorry to question your informatin, but does the bus definitely leave at 8am?
And are there any restaurants or places to buy food on the Mountain or sould we bring our own food.
We will be going thsi month and were wondering if we should bring winter clothes or just semi warm clothes.
Thank you.
